Windows Internet Naming Service


Windows Internet Naming Service (WINS) is a system developed by Microsoft that determines the IP address associated with a particular network computer. This is called name resolution. WINS supports network client and server computers running Windows and can provide name resolution for other computers with special configurations.

Key Takeaways

Three Main Takeaways about Windows Internet Naming Service

  1. Windows Internet Naming Service (WINS) is a legacy computer naming system used in older versions of Microsoft Windows, essentially acting as a database for associating netBIOS names with IP addresses.
  2. Despite its relevancy in older systems, WINS is not typically used in modern networks due to the prevalence of Domain Name System (DNS), which supports more features and is more adaptable to varying network sizes and types.
  3. WINS is a centralized system susceptible to a single point of failure, unlike DNS which makes use of a distributive system. As such, networks still using WINS must implement a secondary or backup WINS server to avoid potential system-wide disruptions.


Windows Internet Naming Service (WINS) is an important technology term because it refers to a system or mapping service used by Microsoft to identify and locate computers in a network. This service operates by associating an IP address with a specific computer or network device on a Microsoft network system, thus making it easier to identify and connect to network resources. WINS serves a crucial role especially in large networks where manual administration of each computer’s information is impractical. By mapping computer names to their IP addresses, WINS allows systems in a network to communicate effectively, facilitating necessary business operations and enhancing overall network efficiency.


Windows Internet Naming Service (WINS) is a system that was designed with the main purpose of managing the association of workstation names and locations with Internet Protocol addresses (IP Addresses) without the user or even an administrator intervention. This technology is substantially used within a network to identify and locate resources by their names. It helps streamline the navigation and usage of resources within complex networks by translating the user-friendly names that humans understand, into addresses that the computer and network equipment understand.Moreover, WINS plays a critical role in minimizing traffic over the network. It does this by limiting the need to broadcast messages to determine the IP address associated with a specific workstation name. Without WINS, there would be an increased volume of broadcasts, which could potentially slow down the overall network performance. Therefore, WINS is not just a name translator, but also a traffic manager, enabling more efficient use of resources within a network.


Windows Internet Naming Service (WINS) is a technology developed by Microsoft to translate NetBIOS names into IP addresses and provide that information to other Windows systems in the network. Below are three real-world examples of how WINS is used:1) **Network Management in Corporate Offices**: In companies with many computers networked together, WINS is used to resolve the hostnames (NetBIOS names) to their corresponding IP addresses. By doing this, it allows users to access resources such as files, printers, or applications on other computers using a familiar name rather than having to know the IP address.2) **Large-scale University or College Networks**: Universities or colleges often have hundreds or thousands of computers connected across various faculties, departments, dorm rooms etc. In cases where these computers are using Microsoft operating systems and networking services, WINS is used to facilitate communication and information sharing among this vast array of network devices.3) **Internet Service Providers (ISP)**: Some Internet Service Providers, that still serve businesses or residences with older, legacy systems might use WINS to better manage their internal network systems. For instance, WINS might be used to facilitate name resolution for servers in their data centers.It’s worth noting that in more recent years, the use of WINS is being phased out in favor of DNS systems, which are considered to be more effective and safer. However, there are still many legacy systems running on older networks where WINS is still utilized.

Frequently Asked Questions(FAQ)

**Q: What is Windows Internet Naming Service (WINS)?**A: Windows Internet Naming Service (WINS) is a system that determines the IP address associated with a particular network computer. It is a service used by Microsoft Windows operating systems to locate computers on a network.**Q: What does WINS do?**A: WINS provides a distributed database for registering and querying dynamic computer name-to-IP address mapping in a routed network environment. It essentially maps IP addresses to computer names to allow computers to locate each other on a network.**Q: Is WINS still used nowadays?**A: WINS is considered an older technology, with newer systems use DNS instead. However, it’s still used in some older networks and for certain applications that rely on it.**Q: Can I use WINS alongside DNS?**A: Yes. WINS and DNS can coexist and complement each other. WINS can cover NetBIOS name resolution in local networks while DNS can do the same for networks that don’t use NetBIOS.**Q: How does WINS differ from DNS?**A: The main difference lies in their purpose. WINS is designed for resolving NetBIOS names, which are names used by devices on a Windows-based network. On the other hand, DNS is designed for resolving domain names on the internet. **Q: Can I use WINS in modern Windows versions?**A: Yes. WINS can be used in modern versions of Windows, but it’s not installed by default. You need to add it via the Add Roles and Features Wizard in the Windows Server Manager.**Q: What port does WINS use?**A: WINS primarily uses TCP and UDP port 42 for communication.**Q: What potential issues might I encounter with WINS?**A: There are several potential issues with WINS since it is an older system, such as entries not being updated correctly, replication errors between WINS servers, or name resolution problems. It’s recommended to use DNS if possible to avoid these issues.
